I find that all brass needs some kind of prep work to get it up to speed,,, a few shots to get it to form to my rifle Chambers,,, then the work begins...
Sort by length incase some needs a few more shots,,, weighing,,, sizing,,, checking neck run-out,,, sorting by primer fit-ment,,, neck thickness and getting them thinned...
I was never a big fan of annealing by flame,,, Ha... Now I have another step to do...
My Leed is a master at brass prep...
Find a manufacturer that supplies you a good quality product and save the extra work...
Lapua Palma Brass has been ok for us over the years,,, even then we give it the going over,,, 1 to 2% discard is about average...
